I initially started watching this show as part of my train chikan project. I don't remember how I found out about the train scene, but I did and here I am writing a review. OK just to preface: this show is basically comprised of short (4min) scenarios involving Keisuke and one of his sisters (not blood related) engaged in various lewd behaviors. There is a focus on big breasts with each girl having huge watermelon-sized tits, as well as pretty prevalent themes such as public sex, defloration, and facials. Other fetishes also make appearances such as lactation, anal, bdsm,soapy massage, train groping, and then something read more

Maybe its becouse i like romance.

I did not really enjoy this. It had no story, which is fine. no humor at all. half the reason i watch anything is to laugh, and be happy about it.

Once again the incest is only there as a 'tack on' adding little to the paper thin plot. Oppai is the dominate theme to this one, along with a varity of common fetishes. none of it particularly struck me as great.

When i watch hentai i like to look for a solid story, romance, with a familar and or relatable setting. the settings were not so intresting. porn movie set, managers read more

Story? Uh... we get to see one guy having sex with his ten sisters, none of which seem to be related to him or to each other by blood ties. That's it. Huh? What are you talking about? Plot twists? Reveals? Character development? What's that? ...Well, one of the ladies in Episode 2 turns out to be... nah, you check it out.

The male lead is plain-looking. All of the ladies are voluptuous, some looking more mature and others a bit younger. Each one has a distinctive design, and their own naughty fetish. Each voice fits each character well. Music and SFX is nothing remarkable, neither read more

WELL, Ane to Boin really very good Hentai. We have two Episodes to Boin, I mean Enjoy.
Story is nice, light we have a MC who has many stepsister and they bang him. So it is kind of a Harem, the past part about it is the situations our MC is in, and how he gets to enjoy these situations to the fullest.
Really good story, with great Design all the sisters are drawn quite sexy and also different from each other, so yes it is not incest, and nobody is blood related.
Each and every character is great in their own way, weather it is the robot read more
